Novel test could improve emphysema diagnosis Posted: 03 Aug 2009 05:00 PM PDT Scientists have developed a novel test for assessing the activity of the matrix metallopeptidase 12 (MMP12) enzyme, which may help improve emphysema diagnosis and accelerate research into other lung diseases in which the enzyme plays a part.

Even low pollution levels reduce lung function in asthmatic children Posted: 03 Aug 2009 05:00 PM PDT Relatively low levels of air pollution are associated with lung function reductions among children with asthma within hours of exposure, researchers have found.

Brain response to dyspnea and pain reduced in asthma patients Posted: 03 Aug 2009 05:00 PM PDT Patients with asthma exhibit down-regulated insular cortex activity in response to dyspnea and pain, indicating a neuronal habituation mechanism that reduces the affective unpleasantness of dyspnea, say researchers.

Schizophrenia prefrontal cortex deficits impede smoking cessation Posted: 03 Aug 2009 05:00 PM PDT Schizophrenia patients who fail to quit smoking appear to have deficits in frontal executive function compared with other patients, say researchers who call for tailored smoking cessation programs.

Adolescent bipolar disorder shows favorable outcomes Posted: 03 Aug 2009 05:00 PM PDT Adolescents with adolescent-onset bipolar disorder with psychotic features have better adult outcomes than those with schizophrenia or schizoaffective disorder, Italian study findings indicate.

Novel warfarin dosing equation developed Posted: 02 Aug 2009 05:00 PM PDT Canadian researchers have developed a group of equations based on readily available information that predicts maintenance warfarin dose in outpatients with venous thromboembolism.

Stroke ‘a rare but devastating’ complication of PCI Posted: 02 Aug 2009 05:00 PM PDT Stroke is a rare but devastating complication in people undergoing percutaneous coronary intervention, associated with older age and more extensive coronary artery disease.

Hot flashes in breast cancer survivors unaffected by tryptophan levels Posted: 02 Aug 2009 05:00 PM PDT In women who have survived breast cancer, physiologically measured and self-reported hot flashes are not increased by acute tryptophan depletion, study results suggest.

Prostate cancer control with hypofractionated EBRT feasible Posted: 02 Aug 2009 05:00 PM PDT Hypofractionation of three-dimensional conformal external-beam radiotherapy for localized prostate cancer does not reduce biochemical control versus standard fractionation, say scientists.

Vitamin D levels predict IVF reproductive success Posted: 02 Aug 2009 05:00 PM PDT Women are more likely to achieve clinical pregnancy following IVF-embryo transfer if they have high serum and follicular fluid vitamin D levels, suggest US study results.

Increased BMI does not affect semen quality in subfertile men Posted: 02 Aug 2009 05:00 PM PDT Dutch study results show that semen quality is not affected by body mass index in subfertile men.

Light exercise during prengnancy does not increase risk for cesarean, instrumental delivery Posted: 02 Aug 2009 05:00 PM PDT Light resistance and toning exercises performed during the second and third trimester of pregnancy do not increase the risk for cesarean or instrumental delivery, or affect the mean dilation, expulsion, and childbirth time, study results show.

Passive smoking during third trimester increases childhood asthma risk Posted: 02 Aug 2009 05:00 PM PDT Pregnant women who are passively exposed to environmental tobacco smoke during the third trimester are at increased risk for delivering a child with asthma- and allergy-related symptoms later in life.

Menopausal low sexual function linked to education, income, menopausal status Posted: 02 Aug 2009 05:00 PM PDT Low sexual function occurs more commonly in post- than in premenopausal women without depression, with low levels of education, low family income, and menopause posing as independent risk factors.

Reporting of hot flashes varies according to measure used Posted: 02 Aug 2009 05:00 PM PDT US study results show dissimilarities between subjective and objective hot flash measures in postmenopausal women initiating aromatase inhibitor treatment for breast cancer.

Nanoparticle therapy potential treatment for ovarian cancer Posted: 02 Aug 2009 05:00 PM PDT Findings from a study conducted in mice suggest that intraperitoneal administration of polymeric nanoparticles to deliver diphtheria toxin -A encoding DNA is an effective treatment for ovarian cancer, thus holding promise for treating humans.

Early-stage ovarian tumors too small for detection Posted: 02 Aug 2009 05:00 PM PDT By analyzing results from prophylactic bilateral salpingo-oophorectomy studies in women carrying the BRCA1 mutation, US researchers have estimated the size and stage distribution of occult serous ovarian cancers, suggesting that a 4-year window exists for early detection.

Over 50 percent chance of live birth after four ART cycles Posted: 02 Aug 2009 05:00 PM PDT A study showing the feasibility of calculating assisted reproductive technology cumulative live-birth rates per individual woman reveals that more than half of women achieve pregnancy in up to four treatment cycles.

Overseas ART accounts for quarter of high order multiple pregnancies Posted: 02 Aug 2009 05:00 PM PDT Fertility treatment performed outside the UK is responsible for over one-quarter of fertility-treated high order multiple pregnancies managed by the UK National Health Service, show study results.

Stearate-enriched plant sterols decrease LDL-C levels Posted: 02 Aug 2009 05:00 PM PDT Dietary consumption of plant sterols enriched in stearate reduces serum concentrations of low-density lipoprotein cholesterol in adults with normal lipid profiles and those with hypercholesterolemia, scientists have demonstrated.

Treatment algorithm brings 71% of patients to LDL-C goal Posted: 02 Aug 2009 05:00 PM PDT Increasing statin dose and incorporating ezetimibe treatment helps patients with dyslipidemia achieve their cholesterol goals in over 70% of cases, show findings from a large, multicenter study.

Higher ICD use in men not explained by less stringent criteria Posted: 02 Aug 2009 05:00 PM PDT Women are only slightly more likely to meet criteria for implantable cardioverter defibrillator implantation than men, a study of a US national registry shows.

Cardiovascular risk in diabetes varies by gender, ethnicity Posted: 02 Aug 2009 05:00 PM PDT Cardiovascular risk profile is generally worse in women than men with diabetes, while risk among women varies according to their ethnicity, findings from the Multi-Ethnic Study of Atherosclerosis indicate.

Vigorous walking best for cardiovascular health in Type 2 diabetes patients Posted: 02 Aug 2009 05:00 PM PDT A lifestyle modification plan that focuses on targeting walking speed is more beneficial for improving markers of cardiovascular health than a program that only targets total daily steps, researchers report.

Higher ICD use in men not explained by less stringent criteria Posted: 02 Aug 2009 05:00 PM PDT Women are only slightly more likely to meet criteria for implantable cardioverter defibrillator implantation than men, a study of a US national registry shows.
